Hhg. Vanes et al., ASSIGNMENT OF THE HUMAN UDP GLUCURONOSYLTRANSFERASE GENE (UGT1A1) TO CHROMOSOME REGION 2Q37, Cytogenetics and cell genetics, 63(2), 1993, pp. 114-116
UDP glucuronosyltransferases (UGTs) comprise a multigene family of dru
g-metabolizing enzymes. The subfamily of UGTs that conjugate bilirubin
and phenolic compounds with glucuronic acid has been termed UGT1A1. I
n man, UGT1A1 isoforms are encoded by a single gene, UGT1A1. Protein i
soforms encoded by UGT1A1 originate by alternative splicing. In the pr
esent study, we used the cDNA of UGT1A14, a bilirubin-conjugating iso
form, to localize the UGT1A1 locus in the human genome. The UGT1A1 gen
e was assigned by in situ hybridization to chromosome region 2q37.
